Remove ExPlat from the project. Replace it with experimentation library from Tracks. (#22354)

* Remove ExPlat logic from the project. Replace it with `experimentation` library from Tracks.

* Provide `AppLogWrapper#e` with `throwable` directly

Otherwise unit tests fail because Mockito has a problem with the synthethic Kotlin method (doesn't see it)

* Fix static code analysis issues

* Remove `experimentation` from the project

There are no currently running experiments, so this integration is redundant. #22354 (review)
